Opis:: The article is a continuation of research on the relationship between forest habitat type and economic aspects of forest management. It assesses the impact of forest habitat types on reforestation costs. As a part of the implementation of the assumed work objectives, economic activities related to afforestation were identified. The research was carried out using the passive experiment method. The research was of registration and observational character. During the acquisition of the necessary data, there was no interference in the forestry work. The costs were analysed in three categories: total costs, tangible costs and intangible costs. Research conducted on the basis of source data obtained from 629 forest plots with a total area of 1100 ha. Based on the results of the research, it was found that the type of forest habitat significantly differentiated all the analyzed costs of reforestation. The forest habitat type differentiated material costs (48%) to a greater extent than intangible costs (43%). In addition, reforestation of deciduous forests has been proven to generate higher forest renewal costs than coniferous forest habitats. The costs of forest regeneration in forest habitats were higher than the costs incurred in coniferous habitats. Information on differences in forest management costs in relation to forest habitats can be used in further research on the forest management support system. The presented research contributes to the development of work on building economic models of the stands. These models must take into account not only the general economic aspects, but also the natural aspects of the forest that affect financial flows related to forest management.

Opis:: On the basis of forest taxation data the presence of European ash in the Bardzkie Mountains area (central part of the Sudety Mountains) was analysed. This included the reckoning of the number of sites and the area covered by ash in various forest habitat types, age classes, altitude zones and on variously slanted and exposed mountain sides. The decline in the number of ashes in younger age classes and complete absence of trees older than 140 years have been noted. In the Bardzkie Mountains ash is the main species forming the forest on mountain riparian forest stands (a 43% participation in the area of forest of this type). Considering the number of specimens most ashes are scattered in mountain broadleaved forest. To the altitude of 650 m ash’ participation in the forest stand composition is stable (30% of analysed locations), but it occupies only 2.6% of total forest area.

Opis:: The aim of the paper is the estimation of hydrological conditions occurring on the area of Przemkowsko- Przecławskie Wetlands in the proposed water management scenarios, which are implemented to restore natural values of the wetland environment .In each of the scenarios, the operation parameters of hydraulic structures were changed, causing the potential increase of ground water alimentation to the wetland area. Common and recognized ground water flow model MODFLOW was used to calculate ground water levels for each scenario and to study the long –term effect of restoration measures on Przemkowsko – Przecławskie Wetlands. Following hydrological characteristics were analysed: mean of the mean ground water levels, inundation frequency, mean ground water amplitude and mean low ground water levels. These characteristics were modeled for the long-term period 1964-1985 for unsteady flow conditions and were compared with the values adopted from intact, reference wetlands. It was proved, that slowing down the outflow of ground water (scenario 1) didn’t provide hydrological conditions desired for the maintenance of swampy habitats. The combination of outflow slow down and restriction of ground water abstraction by existing pumping stations (scenario 2) didn’t guarantee the maintenance of desired values of hydrological characteristics for a swampy habitat as well. The realization of the proposed scenarios enables to keep proper conditions for wet and moist habitats. The management policy for Przemkowsko - Przeclawskie Wetlands should then be directed at the development of those habitats, providing broad realization of environmental protection goals.
W pracy wykorzystano modelowanie przepływu wód podziemnych do obliczenia charakterystyk hydrologicznych wód podziemnych na renaturyzowanym obszarze Bagien Przemkowsko Przecławskich dla różnych wariantów gospodarowania wodą. Analizowane charakterystyki hydrologiczne obejmowały: średnie stany wody, średnie amplitudy zwierciadła wody, częstotliwości zalewu oraz średnie stany niskie. Ich wartości uzyskano dla wieloletniego okresu 1964- 1985 droga modelowania nieustalonego przepływu wód podziemnych, a następnie porównano je z wartościami charakterystyk dla mokradeł referencyjnych Na podstawie tego porównania stwierdzono, że w granicach obiektu badań odtwarzane siedliska odznaczały się warunkami wodnymi korzystnymi dla podmokłych łąk z dominacją ziołorośli i zbiorowisk kaczeńcowych. Warunki takie uzyskano w wariantach gospodarowania wodą zakładających kombinacje spowolnienia odpływu przez urządzenia piętrzące z ograniczeniem ujmowania wód istniejącymi przepompowniami. W wyniku kombinacji takich działań zasilanie podziemne obiektu zwiększa się, stwarzając warunki wodne korzystne dla siedlisk podmokłych i wilgotnych, nie gwarantuje natomiast odtworzenia procesów bagiennych na obszarach chronionych.

Opis:: There is a lack of an acceptable and practical method for calculating the optimal moment at which a forest stand is considered ready for felling. The aim of the research was to: (1) develop a concept for the calculation of the rotation age for forest stands based on economic criteria and (2) develop a methodology for obtaining and processing empirical data necessary for such calculation. It is assumed that stands are felled at the age affecting the age structure (area of age classes) of a forest in such a way that the difference between revenues from the sale of timber harvested in inter−mediate cuts and final cuts and the costs of timber harvest, silvicultural management, forest protection and administration is the largest. The developed method of calculating the rotation age was tested on the example of three Scots pine forests under the clear−cutting system representing typical forest habitats. The collected empirical material consisted of (1) own measurement data used to determine the value of the growing stock, and (2) data from the State Forests Information System used to determine the management costs, timber prices and the volume of timber harvested from intermediate cuts. These data helped to calculate the relationship between the income from a forest (including: revenues from the final and intermediate cuts, costs of forest management as well as timber harvesting and extraction) and the rotation age. The highest net income was when the rotation age was 108−125 years. The more fertile habitat, the shorter was the rotation age. The proposed methodology can be treated as a useful tool for the calculation of rotation age related to forest management in Poland. The dependence of income from a forest on the rotation age can be used to calculate losses that may arise when other than an optimal rotation age is applied.

Opis:: Environment creating and general social cost−consuming factors are of the utmost importance to realize the multifunctional forest management. As a result, in some forest districts, one notes a disproportionate relationship between the costs and incomes. It can determine the level of the achieved profitability and influence the availability of the financial resources. One of the crucial elements of the realization of the forest management is the constant control of the cash flow (income and costs). Because of the specification of the forest management, the flows are determined by the economic as well as ecological factors. This is the reason of exploring of the influence of forest habitat types on the sales income reached as part of the early and late thinning for positive selection. The income from the sales of 100,798 m3 woody raw material acquired from 3,628 ha was analyzed. Forest habitat type significantly influenced the income taken from the sale of woody raw material that was reached as the part of analyzed tending (V=44%). It was proved that forest habitat type in case of early thinning for positive selection had higher all−important influence on the income acquired from the sale of wood than in case of late thinning for positive selection, which was determined as the middle influence (V=56 and 24%, respectively).

Opis:: Integrating the economic aspects of forest management (cost) with ecological elements of timber production (habitat type) significantly contributes to a better understanding of forest growth and utilisation. The type of silvicultural treatments and forest habitat types determine number of economic activities carried out in the stands and have an important impact on the associated costs. The aim of the study was to describe the impact of silviculture treatments and types of forest habitat on unit timber harvesting cost. We summarised the cost of timber logging depending on the harvest practices and types of habitats. In total, costs of treatments performed on the 2.5 thousand ha area were analysed. Obtained results were combined in relation to average unit costs of raw timber logging from individual habitats and silviculture treatments such as late cleanings and thinnings. The studied impact was assessed with standard deviation (SD) based on the assumption that the higher its value, the more important role of silvicultural treatments and forest habitats in defining the cost of raw timber harvesting. Our study showed that both factors (type of forest habitat and silvicultural treatment) had an effect on variability of timber logging costs. Comparing deciduous and coniferous habitats, higher costs were reported for the latter one. The highest unit cost of timber logging was found on the fresh coniferous habitat, while the lowest on the wet mixed forest. Moreover, the highest cost was reported for timber raw material harvested from late cleanings and the lowest from late thinnings. SD of the average cost of timber harvest ranged from 12.67 to 13.53 PLN depending on the silviculture treatments and from 0.68 to 2.39 PLN depending on the forest type. Our findings are important preliminary steps in broader study regarding revenues generated from forest stands growing on different habitats. Eventually it would help in assessing the profitability of economic activity that depends on environmental conditions of forest management.

Opis:: The study presents the results of MANOVA of tree slenderness. The study material comprised 72 larch trees in a dominant stand of different age classes growing in fresh mixed coniferous (BMśw), fresh mixed deciduous (LMśw) and fresh deciduous (Lśw) forest habitats. The slenderness of each larch tree was calculated as the ratio of tree height [m] to breast height diameter [cm]. Basic statistical characteristics were also established. A three−way analysis of variance was performed assessing the statistical significance of the impact of forest habitat type, age and biosocial position of trees in the stand. A similar analysis was done for two basic measurement characteristics of trees – breast height diameter and height.

Opis:: Presence of plant species, associated with ancient forests (continuous existence >200 years) can be used for assessing woodland biodiversity. The aim of this study is to specify which plant species, included in the ancient forests plant species list, can indicate old woodlands in parks and what plant features are characteristic for certain habitat types. Richest in ancient forest plant species are those fragments of woodlands, which have existed continuously for at least 120 years, and their fragments suffered least from human pressure during that time, whereas recent woodlands are characterized by a small share of ancient forest indicator species and domination of nitrophilous species. Investigated plants usually propagate vegetatively, their seeds are of a small size and they have regularly, densely set leaves. Plants associated with ancient woodlands are good indicators of woodland continuity in parks so they can be used for age assessment in these areas. Accumulation of such plants can be a useful criterion in parks evaluation. Proposed idea of sustainable management of a park space, including selection of areas of a great ecological value, can be a chance to preserve woodland biodiversity.

Opis:: W artykule przedstawiono opracowany przez Edwarda Bartmana projekt Ogrodu Botanicznego w Bydgoszczy, powstały u schyłku lat 70. XX w. Główny ciężar położono na przyjętą ideę projektową, a nie na jego stan dzisiejszy, gdyż stopień realizacji projektu oraz wprowadzone w jej trakcie zmiany (m.in. brak części centralnej i wejściowej, o najbogatszym w założeniu programie) istotnie zaburzyły autorską wizję ogrodu zarówno w sferze kompozycji, jak i funkcji. Pominięto również informacje o dzisiejszych zasobach roślinnych ogrodu, te bowiem stanowią odrębne zagadnienie. Projekt bydgoskiego ogrodu to przykład zastosowania nowoczesnej myśli w architekturze krajobrazu, przełamującej wcześniejsze schematy, które traktowały ogrody botaniczne jako miejsce gromadzenia jak największej liczby gatunków roślin uporządkowanych głównie według klucza systematycznego. W autorskim zamierzeniu miał to być obiekt, w którego projekcie położono silny akcent na relacje pomiędzy człowiekiem a naturą, z poszanowaniem praw przyrody i zasad ekologii. Jednocześnie powstawał w zgodzie z ówczesnymi tendencjami budowy ogrodów botanicznych – jako obiekt podmiejski (ze względu na większy areał i zapewnienie dalszego rozwoju) oraz jako jeden z elementów zespołu wielofunkcyjnego, tzw. parku kultury. Podstawowym materiałem źródłowym wykorzystanym w artykule były zachowane oryginalne rysunki prof. E. Bartmana oraz opracowania pochodzące z jego prywatnych zbiorów. Analizując formę (kompozycję) i program tego ogrodu, można wyróżnić trzy podstawowe idee, zgodnie z którymi powstawał: poszanowanie naturalnie występujących siedlisk roślinnych, które wyznaczyły ramy kompozycyjne i doborów gatunkowych (względy filozoficzne oraz ekonomiczne); otwarcie obiektu na potrzeby rekreacyjne i poznawcze człowieka oraz założenie, że ogród będzie dostępny i będzie funkcjonował przez cały rok (m.in. dzięki rezygnacji z ogrodzeń oraz wprowadzeniu atrakcyjnego, całorocznego programu funkcjonalnego – muzeum, audytorium, kawiarnie i ogrody zimowe). To połączenie pozwoliło, by powstał oryginalny i wybiegający poza ówczesne konwencje projekt. Niestety, zamierzenia projektowe zrealizowano tylko częściowo, czym znacząco upośledzono funkcjonowanie tego obiektu.
In this article, the project of the Botanic Garden in Bydgoszcz, as developed by Edward Bartman was created at the end of the 1970s has been presented. The main emphasis was put on the adopted idea of the project and not on its current state as the degree of implementation of the project and the changes, being introduced during the mentioned process (inter alia, lack of the central entrance part in the project with the richest assumed programme) have significantly disturbed the author’s vision of the garden in the sphere of composition as well as its functions. There was also omitted information on the present plant reserves because they constitute a separate problem. The project of the Bydgoszcz garden is an example of the modern approach to landscape architecture, breaking down the earlier schemes of constructing botanic gardens, treated as a place for accumulation of the possibly greatest number of plant species, arranged mainly according to a systematic key. In the intention of the author, it was to be an object which strongly emphasizes the relations between man and nature, with respect to natural laws and ecology principles. At the same time, it was founded on conformity with the contemporary tendencies of constructing botanic gardens – as a suburban object (due to a greater area and ensuring further development) and one of the elements of multifunctional object, i.e. park of culture. The basic source material included original drawings and elaborations, coming from private collections of Prof. E. Bartman, the main architect of the Garden. When analyzing the form (composition) and program of the discussed garden, we may distinguish three basic ideas, according to which it was constructed: respecting the naturally o curring plant habitats which outline the compositional frames and the species selection (philosophical and economical aspects); opening of the object to the recreational and cognitive needs of man, with preservation of almost complete availability of the object (owing to, inter alia, giving up of fencing and introduction of attractive, all-year functioning program – museum, auditorium, cafe houses and winter gardens). The mentioned combination allowed creating the original, going ahead project. Unfortunately, the project assumptions have been only partially implemented and functioning of the discussed object has been impaired.

Opis:: The article presents the size and weight of needles in 30−year−old Scots pine stands over one year with regard to the site conditions in which they grow (fresh mixed coniferous and fresh coniferous habitats). Two rectangular 1−hectare sample plots, which differed from one another only with the habitat type, were set up in Maszewo forestry in the Cybinka Forest District (western Poland). The plots were divided into 100 one−acre subplots, which were ascribed numbers from 1 to 100. In order to pick 10 plots a random number generator was used. The middle of the chosen plot became the central point of the 1−acre circular sample plots, where the measurements of all diameters at breast height and the height of every fifth tree were taken. Moreover, it was also the place where a square needle collection container (20 cm high, 1 m2 area) was located. The empty containers were placed in both experimental plots on 1st August 2017 and they were emptied on the first day of each month, throughout the entire year. The entire material was dried at the temperature of 65°C with an induced air flow. The needle mass was measured with the accuracy up to 0.001 g. Out of the samples collected each month, 300 needles were chosen at random in order to measure their length (after they were scanned with WinFOLIA program the size of each individual needle was established). Throughout the entire year, on fresh coniferous habitat the mass of the fallen needles was 2.8203 t/ha and it was by over 20% higher than it was determined for the fresh coniferous habitat. The lowest mass of the needle fall in each stand was in January, and the greatest in September on the fresh coniferous habitat, whereas in October on the fresh mixed coniferous habitat. In both of these cases, it was more than a half of the needle mass for the entire year. The average length of the fallen needles was in each month smaller on the fresh coniferous habitat and the differences between the analyzed stands were significant. The difference was the smallest (3.3%) in May, while the greatest (18.8%) in February. Moreover, significant differences in the length of the needles in the particular months in both types of stands were observed. The coefficient of variation for the needles length on the fresh mixed coniferous habitat ranged from 17.4 to 22.8%, whereas on the other habitat it varied between 14.2 and 21.6%. The mean of the coefficients of variation for the particular months was lower by 2.0% and for fresh coniferous habitat it reached 18.25%.

Opis:: The study presents the results of the MANOVA investigation on single tree growth space. The study included 48 larch trees in a dominant stand of different age classes growing in the fresh mixed coniferous (BMśw) and fresh mixed broadleaved (LMśw) forest habitats. The space occupied by a single tree was calculated for each larch tree as the volume of a cylinder with a height equal to the height of a tree, while the base area was determined from the average crown radius. Basic statistical characteristics were established. The MANOVA was performed to assess the statistical significance of the impact of forest habitat type, age and biosocial position of trees in a stand. A similar analysis was done for two basic measurement characteristics of trees – diameter at breast height and height.

Opis:: The aim of the research was to determine the habitat−related variation in the selected structural and physical−mechanical properties of silver birch. Two sample plots were established in the territory of the Biała Podlaska Forest District in eastern Poland. Samples for measurement were taken from the plots with trees aged 45−50 years growing in the fresh deciduous (Lśw) and fresh mixed deciduous (LMśw) forest habitats. The following properties were subjected to statistical analysis: the average width of annual rings, wood density determined for the samples of 20×20×300 mm, 20×20×30 mm, and 30×2.66×0.1 mm in size (the last dimension parallel to grain), tensile strength parallel to grain, compression strength parallel to grain, static bending, modulus of elasticity in static bending and the coefficients of tensile strength parallel to grain, compression parallel to grain, static bending, and modulus of elasticity in static bending. The research confirmed a significant effect of the habitat on the mean values of birch wood density for all examined sample sizes, tensile strength parallel to grain, static bending and modulus of elasticity in static bending. No significant effect of the habitat on the mean values of annual ring width, tensile strength parallel to grain and the coefficients of tensile strength parallel to grain, compression strength parallel to grain, static bending and modulus of elasticity in static bending for birch wood samples was found.

Opis:: Chemical properties and fertility of soils were compared under spruce, mixed and beech stands in four types of forest habitat (mountain broadleaf forest, mountain mixed broadleaf forest, mountain mixed coniferous forest and mountain coniferous forest) in 373 sites of forest monitoring in the Stołowe Mountains National Park, SW Poland. Soils under the spruce stands had higher organic carbon pools in their upper horizons, but lower pH, increased activity of exchangeable aluminum, lower contents of exchangeable base cations, available potassium and magnesium, resulting finally in lower values of the soil trophic index (SIG). The negative impact of spruce monocultures on the physicochemical soil properties was much stronger in the eutrophic habitats (dedicated to broadleaf forest) than in dystrophic ones. Weak positive effect of the beech introduction on soils in the dystrophic habitats indicated that the conversion of the coniferous into mixed or deciduous stands would not cause a rapid improvement in the physicochemical properties deformed previously under spruce monocultures.

Opis:: The study presents the relationships between larch slenderness and age, breast height diameter, height, crown width, crown projection area, crown length and habitat type. The study comprised larch trees in a dominant stand of different age classes growing in fresh mixed coniferous (BMśw), fresh mixed deciduous (LMśw) and fresh deciduous (Lśw) forest habitats. The slenderness of each larch was calculated as the ratio of tree height to breast height diameter. The crown projection area was calculated as a circle with a radius equal to the average radius of the crown. The average crown radius was established after its projection in the four main geographical directions. The crown length was calculated as the difference between the height of a tree and the height of crown location. Also an attempt was made to describe tree slenderness using multiple regression equations.

Opis:: Paper presents analysis of differences in conventional wood density of Scots pine measured at breast height regarding the geographical location of stands, forest habitat type, stand age and associated parameters such as density in the mid−length of the stem, density in the upper end of the stem and diameter at breast height. To investigate the impact of these factors, an analysis of covariance was used in accordance with two models specifically developed for this purpose. We found dependence of conventional wood density on the type of forest habitat and geographical location of the stand. The highest density was detected in dry coniferous forests, while the smallest in fresh mixed coniferous forests. Scots pine wood from Zielona Góra Forest (western Poland) characterised with the highest density, while from the Knyszyn Primeval Forest (eastern Poland)− with the lowest.

Opis:: The objective of the research was to determine the effect of habitat type of selected species of trees on the nature of cooccurrence of Fe, Mn, Zn, Cu, Pb, Cd, Ni, Cr and Co. The presence of speciation forms of these metals was investigated, with reference to the species composition of tree stands in selected areas of the Tatra Mountain National Park (Chochołowska Valley, Strążyska Valley, Kościeliska Valley, as well as Mała Łąka Valley). Contents of selected metals in samples were determined by the flame ASA method, with an accuracy of 0.1 μg/g. In habitats dominated by maples, the Pb content in the Chochołowska Valley, unlike Kościeliska Valley covered with beeches, the Pb content in the form directly bioavailable, was twice as high. This was clearly proved in the case of Strążyska Valley where the soil in beech tree habitats contained larger quantities of exchangeable forms of Pb, than that in the Chochołowska Valley. The soil of the valleys, including the Mała Łąka Valley, showed peculiar characteristic averaging of the contents of selected speciation forms of metals in the soil. Content corresponding to 10 percentile and geometrical average may be regarded as benchmarks in future studies of the Tatra Mountain National Park, or other protected areas.

Nakłady pracy zagospodarowania i użytkowania lasu charakteryzują się dużym zróżnicowaniem ich wielkości w zależności od typu siedliska w górach. Najmniejsze nakłady pracy występują na siedlisku najuboższym Bór Wysokogórski i wynoszą odpowiednio na hodowlę 481 rbhźha-1, ochronę 291 rbhźha-1 oraz użytkowanie 911 rbhźha-1 i wzrastają w miarę polepszania się typu siedliskowego lasu i najwyższe występują na siedlisku Las Górski i wynoszą odpowiednio 1031 rbhźha-1, 341 rbhźha-1 i 2877 rbhźha-1.
The paper presents results of the research concerning the impact of mountain forest biotopic type on the amount of labour for forest management and use. The amount of labour for forest management and use is highly diversified depending on the type of habitat in the mountains. Lowest amount of labour has been observed in the poorest habitat of Bór Wysokogórski, reaching respectively: 481 man-hoursźha-1 for breeding, 291 man-hoursźha-1 for protection, and 911 man-hoursźha-1 for use. These values tend to grow with improving forest biotopic type, and they are highest in the habitat of Las Górski, reaching respectively: 1031 man-hoursźha-1, 341 man-hoursźha-1 and 2877 man-hoursźha-1.

Opis:: The paper shows the use of Kohonen's network for classification of basaltoides on the base of chemical properties of soils and Polypodium vulgare L. The study area was Lower Silesia (Poland). The archival data were: chemical composition of types of basaltoides from 89 sites (Al2O3, CaO, FeO, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SiO2 and TiO2), elements contents in soils (Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, S, Ti and Zn) and leaves of P. vulgare (Ca, Cd, Co, Cu, Fe, K, Mg, Mn, Mo, N, Ni, P, Pb, S, Ti and Zn) from 20 sites. Descriptive statistical parameters of soils and leaves chemical properties have been shown, statistical analyses using ANOVA and relationships between chemical elements were carried out, and SOFM models have been constructed. The study revealed that the ordination of individuals and groups of neurons in topological maps of plant and soil chemical properties are similar. The constructed models are related with significantly different contents of elements in plants and soils. These models represent different chemical types of soils and are connected with ordination of types of basaltoides worked out by SOFM model of TAS division. The SOFM appeared to be a useful technique for ordination of ecological data and provides a novel framework for the discovery and forecasting of ecosystem properties.
